Each year the BMW Berlin Marathon attracts 40,000 runners aiming for their own record time. It's flat, traffic-free, filled with incredible atmosphere that altogether pave the way for the fast time... This year, in the 50th anniversary of the marathon, the event is more desirable than ever. Therefore, I'm determined not only to take part but even more so to run my socks off to achieve my PB whilst raising money for Save the Children.

Once again, I am not alone in my quest. Six of my colleagues from GSK will also run this iconic marathon. Each of us pledged to raise a minimum £1000 (1200 Euros) to support the incredible work Save the Children does worldwide. GSK will match pound for pound all your donations to make our efforts even more worthwhile!
